Abstract: Disclosed is a non-coaxial projection light source system including a light source, a fluorescent wheel, and a converging shaping lens group located between the light source and the fluorescent wheel. Excitation light emitted by the light source is emitted to the converging shaping lens group in an optical axis direction inclined to the converging shaping lens group and then is emitted to the fluorescent wheel. Radiating fluorescent light generated by excitation on the fluorescent wheel is emitted to the converging shaping lens group and then is converged to a light path direction different from the excitation light to be output.
